Recommended: Role of the stethoscope in healthcare
Stethoscope functionality generally has not changed over the past few decades evolving from the monaural hollowed out wooden tube first invented in the early 1800’s by Rene Laennec to the more familiar long multi tubular version, improved upon by George Cammann 50 years later, we so typically see today. The core components of a modern stethoscope are comprised of ear tips, binaural piece, tubing and a diaphragm with a bell on the back. The bell transmits low frequency waves all the way up to the ear pieces, while the diaphragm is designed to carry the higher frequency sound. The two fathers of the stethoscope left little room for improvement on the near perfect design for just over a century until a Harvard Medical School professor by the name of David Littmann turned the simple listening device into the versatile diagnostic tool resting around almost every health care professional’s neck today. …show more content…
Many top tier lists have the brand mentioned in at least one position and some have even had more than half of their spots taken over by their many variations of the stethoscope. There is no perfect product out there, especially in a field as diverse as the medical industry, and each piece of equipment brings their own special feature so it really comes down to what one is looking for in the product. As with any market, there is usually always at least one product that shines out above the rest, often having two rival products battling it out for top spot. However in the stethoscope industry, it is hard to find a product to rival the quality of the Littmann line of products. The Littmann Cardiology III stethoscope is often thought to be one of the best stethoscopes money can buy, but at a premium price of nearly $200, what exactly are you spending your money on for that kind of
Transcatheter aortic valve replacement or TAVR is the latest technology used principally for the treatment of aortic stenosis, a condition in which one of the major valves of the heart, the aortic valve, becomes tight and stiff, usually as a result of aging (3). Since many patients who need aortic valve replacement for aortic stenosis are too sick to undergo major valve replacement surgery, they are unable to get the treatment they need. With the transcatheter aortic valve, this issue is bypassed because this valve can be implanted in the heart by accessing the patient’s heart through an artery in the groin. The valve can be inserted through a wire that can be pushed to the heart and the old valve is simply pushed to the side when the new valve is implanted. This technology has been in use in the US with Edwards’ Sapiens valve since 2011 and has saved the lives of many patients with aortic stenosis (4). Medtronic’s CoreValve uses similar technology and has won patent fights in Europe and has been in use internationally. However, within U.S., Medtronic has not been...
Cochlear implants are amazing feats of biomedical engineering, and have helped many people regain the ability to hear. While there are some ethical dilemmas that go along with them, there is no denying just how amazing these implants really are. By understanding how the ear works, what causes it to stop working, and using science and engineering to fix that problem, there is now a way to give someone a sense they might have never been able to experience. It can be costly, but it could drastically change someone’s life. Some people may say for worse, but there will always be someone else to say it was for better. Overall, cochlear implants are an incredible invention and will continue to grow and only get better with technology.
Without question the cost of medical care in this country has skyrocketed over the last few decades. Walk into an emergency room with an earache or the need for a few stitches and you’re apt to walk out with a bill that is nothing short of shocking.
As we go through our daily routine in our jobs in any medical facilities, we are bound to make an occasional error. Misspelling a word on a chart may be one of them. If you make a mistake while you are writing in a patient's medical chart, just draw one straight line through the word and put your initials to the top right of it, and write what you meant to say next to it. Do not make any big swirly lines through the incorrect word. The chart must look as neat and professional as possible. You might try to keep track of the mistakes you make so you can be sure not to make them in the future. Common sense, I know. But this could make a huge difference in the medical profession concerning someone's life.
Therefore, I plan on closely examining audiology not only in a clinical setting but also in a research setting after my first year in USF’s program. I plan on closely examining innovative audiological strategies, as a graduate student, inside and outside of the classroom, while immersing myself in the intellectual community within the department. While my future classmates at USF may claim that they were born audiologists, I am proud to proclaim, as I have reflected on my journey thus far, that I have gained an intellect and love for audiology that drives my unrelenting passion for the field.
Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies and is provided by obstetric and gynecologic sonographers, who also provide imaging of the female reproductive system. Other types of sonography include; abdominal sonography, breast sonography, musculoskeletal sonography, neurosonography and cardiovascular sonography. Due to the vast nature of uses in sonography, most professionals study one field that they choose to specialize in. Diagnostic medical sonography is a rapidly growing field because of the increase in medical advances. The area of Cleveland, Ohio has continued to rise in the medical field with great strides, providing better career prospects with the availability of numerous employment positions.
A.B. reports smoking a pack of cigarettes a day for the last thirty years. He denies drinking alcohol or using street drugs. While he has insurance through his union, it does not cover the entire cost of his medications and he states that he does not have a stable primary care
October 9th, 2016, after being discharged just three days prior, a 44-year-old African American female presented in the emergency department with complaints of shortness of breath with minimal activity and chest pain that radiates to the back and shoulders. Vitals signs were taken and reveled a heart rate of 134, blood pressure of 219/147 and a respiratory rate 28. Observation of the patient showed that she was slightly diaphoretic and anxious. Lab work was ordered to be drawn as well as an ECG and the admission process began. Admitting diagnosis recorded was tachycardia, elevated troponin, acute exacerbation of congestive heart failure, acute chronic congestive heart failure, chest pain and pleuritic chest pain.
The most common model of the ancestral hearing aid is that of the simple ear trumpet. This was a small, pipe-looking device which was carved from either bull’s horn or seashell, and was held up to the ear in order to amplify sound. The audible result of such would have been much like cupping your hand around your ear.

Tess’ job also includes monitoring patients through the first recovery stages after an operation administering the appropriate medications during recovery and prescribing medication for those living with chronic pain.
Being able to identify lumps, swelling, tissue damage, cysts, and the overwhelming news of the sex of a baby all have something in common, an ultrasound. Swelling of the spleen, kidney stones, blood clots, aneurysms, cancer and so much more can be identified through the works of an ultrasound’s imaging technique. Ultrasound involves many concepts, procedures, and careers. The amount of medical possibilities involved with ultrasounds is useful in major medical diagnostics. The field of ultrasounds and career opportunities are widely growing. As medical careers flourish, needs for technicians in many fields of medicine are increasing. Instead of a doctor choosing complex and risky surgery to find out problems within the body, they can now choose a safer path; the ultrasound path. Patient’s history and physical evaluation are building blocks to diagnostics but ultrasounds are much greater. They are powerful tools used to see beyond the skin into the depths of a person’s body. What ultrasounds are, what types there are, and what they are used for, and the education and careers available are the major themes found in research on the subject. Knowledge of ultrasound and its background may help one decide what career is best for them. Understanding the wide array of diagnostic tests and their uses are essential to figuring out what a career as a sonographer entails and the type of education that is needed. Because there are plenty of possibilities for specializing with different technologies, there is a wide variety of job opportunities in the medical imaging career. The call for ultrasound’s assistance opens new paths in future high-quality careers.
The amount of career opportunities involved with the profession are endless. Virtual Job Shadow estimates that there are about 75,000 Ultrasound Technicians in the world and half are working in hospitals. By far, hospitals are the most common employers for sonographers but doctor’s offices are not too far behind. Labs, rehabilitation centers, and nursing homes are other establishments that Ultrasound Technicians can be found. These jobs are highly competitive and they demand a high level of attention and accuracy. As medical careers flourish, needs for technicians in many fields of medicine are increasing. Instead of a doctor choosing complex and risky surgery to find out problems within the body, they can now choose a safer path; the ultrasound path. Patient’s history and physical evaluation are building blocks to diagnostics but ultrasounds are much greater. While the field of Ultrasound Technology is a popular in the health care industry, there are still a fairly small number of people in the
In conclusion, after measurements were recorded for four weeks the evaluators came to the conclusion that researched “showed no significant differences between the SEIC and ultrasound groups” in the visual analog scale, the pain pressure threshold, or the cervical lateral flexion. The article does include graphs of the particular
